POLYETHYLENE/WOOD FLOUR/CLAY NANOCOMPOSITE WHICH CAN PROVIDE PRODUCT WITH ADVANTAGES OF PLASTIC AND NATURAL WOOD

摘要

PURPOSE: A polyethylene/wood flour/clay nanocomposite is provided to ensure excellent mechanical strength, thermal stability, dimensional stability and profitability due to use of waste wood or small piece wood.;CONSTITUTION: A polyethylene/wood flour/clay nanocomposite is prepared by the steps of: mixing 60 parts by weight of polyethylene and 3 parts by weight of compatibilizers(MA-g-PE) in a melt-blending condition of 150°C and 60rpm for 4 hours; injecting 1 part by weight of nanoclay based on the total amount of the polyethylene/wood flour/compatibilizers and melting the mixture; and injecting 40 parts by weight of 70~150μm wood dust and melting them.;COPYRIGHT KIPO 2011
